$B_{c} \to η_{c}$ form factors at large recoil: Interplay of soft-quark and soft-gluon dynamics

Guido Bell, Philipp Böer, Thorsten Feldmann +2

We perform an all-order analysis of double-logarithmic corrections to the so-called soft-overlap contribution to heavy-to-light transition form factors at large hadronic recoil. Sp…

Renormalisation group evolution of the shape function $g_{17}$ in $B ˉ \to X_{s} γ$ and $B ˉ \to X_{s} ℓ^{+} ℓ^{-}$ at subleading power

Riccardo Bartocci, Philipp Böer, Tobias Hurth

We derive and solve the renormalisation-group (RG) equation of the shape function $g_{17} (ω, ω_{1}; μ)$ , which appears at subleading power in the factorization of the inclusive decays…
